From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I always try to consult the man pages for these kind of questions (you can search by typing '/' in the man page). Here's what the systemctl manual has to say in the specifications for the
--forceoption:Note that when --force is specified twice the selected operation is executed by systemctl itself, and the system manager is not contacted. This means the command should succeed even when the system manager has crashed.I would use the man pages but my working laptop uses Windows and since the system died i dont have any way to check them until I get home.
Thank you a lot for the answer though, that does explain a lot!
Manpages.org
It sounds like it should be a hookup app, but it actually is the online Linux man pages.
Or, for a less dubious sounding site, man7.org
man7 and such are better. This runs google analytics, and cannot work when fetch requests are disabled (also suitable for sending back anything), let alone disabling scripts
oftentimes (and this is more of a general statement) throwing into google exactly what you would otherwise type into your shell of choice should get you on the right track, ie searching for "man systemctl"
as far as the inability to reboot goes, if a regular
sudo rebootcan't bring the machine back up either then this is probably a hardware issue outside the sphere of the operating system's influence. can't say I experienced something like that myself. I guess the closest I witnessed would be a computer that when rebooted with an old USB-Keyboard plugged in just refused to get past the POST screen. The keyboard worked fine if plugged in later, but the computer couldn't reliably get through the boot process with the thing present. Maybe there's a similar variable to your setup.honestly glad you made the thread still cause I just love questions like this to see if I can answer them and if I can't I learn something
Weird choice tbh. I'd make --force --force a separate option if possible.
You just really force it.
It's like with
-vin various applications.-vmeans "verbose", and-vvmeans "really verbose", and-vvvmeans "an ungodly amount of data printed to the terminal, so much that it might crash".But that's all part of the same argument. If it was
-for-ffthat'd make sense. Duplicate parameters are usually ignored in like all other programs I can think of.The
-vvvI know is the same as-v -v -v. Can't check right now, but is the short parameter-f? So maybe give-ffa try ...It's a dangerous command - I'd rather not run it by accidentally hitting the
fkey a second time.I agree. Specifying the same param twice like this feels like it should be idempotent. Sometimes a final cmdline string is built by multiple tools concatenating their outputs together; if each one adds
--forcewithout any way to know if it's already been added elsewhere, this could lead to undesirable behavior.Even
--forceforcewould be better.--force-and-I-really-mean-it-this-time
Yeah, duplicate flags should just be ignored.
swear, but it is funny
In other words, RTFM
